FAQs
When installing CB1633T120480GAX, plan for a top-feed arrangement and three-pole wiring within a UL Listed enclosure. Place the switch in a compliant panel or MCC with appropriate clearances, ensure proper control wiring for the 120 V circuit, and verify compatibility with optional ground fault relay or blown-fuse detection as needed. For safe operation, follow Eaton installation notes and Kirk provisions or auxiliary contact provisions if expansion is anticipated.
The device is designed for high-current, 480V distributions, offering 1600A amperage rating with a three-pole configuration and fusible protection. This combination provides fast fault isolation, robust current handling, and dependable coordination with upstream breakers. In practice, this reduces arc energy exposure and improves overall system reliability in heavy-load environments such as conveyors, presses, and large motors.
Yes, the CB1633T120480GAX is UL Listed, which supports safety and regulatory compliance for commercial and industrial installations. It also carries NEMA enclosure ratings of 1, 3R, 4, and 12, indicating suitability for indoor, damp, and harsh environments. While other certifications like CE or IP ratings are not specified in the data, UL Listing plus NEMA ratings provide strong protection and compliance context for typical plant applications.
Optional features include Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions. These options enhance fault detection accuracy, enable selective tripping, and support remote signaling and interlocking with other Eaton devices. They reduce downtime, improve diagnostic capabilities, and simplify integration into complex protection schemes.
